Using the results from students' mistakes to make interferential options (confused plans) in multiple choice questions will help teachers analyze the wrong situations and take corrective measures. With the learner's error-based teaching method, students will remember their mistakes and avoid repeating the same mistakes in learning. Multiple choice questions are widely used in the annual National High School Exam in Vietnam. However, in order to assess students' mistakes in the process of organizing teaching and learning in high schools, the design of multiple choice questions should focus on the results of the interferential options. From analyzing the results from wrong situations, the interferential options are strong enough to assess the impact from mistakes.
